Many basic salts contain hydroxide, which is a compound of a metal with the hydroxide ion OH−
There is no reaction. "Hydroxide acid" is water, which does not react with sodium hydroxide.
acid+ metal oxide --> salt + water
Metal Hydroxide + Acid = Metal Salt + Water
Sodium hydroxide is obtained from salt, yes. The manufacture of this strong base is accomplished mainly from what is termed the chloralkali process. This is the electrolysis of a salt solution which produces sodium hydroxide and also chlorine and hydrogen gas. It is an industrial process that is important to the chemical industry. A link follows.
metallc hydroxide.
Barium hydroxide - Ba(OH)2 - is a hydroxide.
A salt is made up of the anion of an acid the cation of a base. Potassium hydroxide is not a salt because it is a base itself.

Aluminum hydroxide is a salt, no charge. In solution, it is alkaline.
yes

Metallic hydroxide.
acid+ metal oxide --> salt + water
Metal Hydroxide + Acid = Metal Salt + Water
NaOH - sodium hydroxide
a metal salt that contains the hydroxide ion, OH- For example sodium hydroxide, NaOH, calcium hydroxide, Ca(OH)2
